Carextussock plays an important role in supporting biodiversity and carbon sequestration of wetland ecosystems, while it is highly threatened by climate change and anthropogenic activities. Therefore, identifying the potential distribution patterns of Carextussocks wetland is vital for their targeted conservation and restoration. The current and future (2050s and 2070s) potential habitats distribution of Carextussocks in Northeast China were predicted using a Maximum Entropy (Maxent) model based on 68 current data of Carextussock distributions and three groups of environmental variables (bioclimate, topography, soil properties). Results show that isothermality, seasonal precipitation variability and altitude are important factors that determine the distribution of Carextussock. The high suitable habitat of Carextussock is about 5.7 × 104km2and mainly distributed in the Sanjiang Plain, Songnen Plain, Changbai Mountains and Da Hinggan Mountains. The area of stable habitats of Carextussock is significantly higher than the lost and expanded habitats in the future climate scenarios, and the unsuitable habitats mainly occur in Da Hinggan Mountains, Xiao Hinggan Mountains and Changbai Mountains. Overall, Carextussock wetlands at high altitude and high latitude are more sensitive to climate change, and more attention should be invested in high latitude and high altitude areas.
